OIL-BURNER.

To all whom t may concern: l

Be it known that I, WILLIAM B. BAILEY, a citizen of the United States, residing at Seattle, in the vcounty of King and State of Washington, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to liquid hydrocarbon burners and, more especially, to that class of oil burners which are adapted to be used in stoves or furnaces `of ordinary construction.

The object of the invention is-to provide a burner of this character wherein the oil will be thoroughly vaporized and mixed with a `suitable quantity of air at a high temperature to produce a highly combustible gas with an absence of smoke and soot.

The invention consists in the novel construction, adaptation and combination of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevational view of an oil burner embodying my invention. Fig. 2 is a longitudinal Vertical section of the same. Fig. 3 is a. sectional view taken substantially on broken lines 3-3 of Fig. 5. Figs. 4, 5 and 6 are transverse sectional views through 4 4, 5-5- and 6-6 'of Fig. 2. Fig. 7 is a perspective view of the air inlet valve, shown detached.

The reference numeral 10 designates a casing formed with upwardly converging side walls 101 and a centrally arranged tunnel 11 in its underside. In the casing leg members 12 at opposite sides of said tunnel are longitudinal wing iues 13 connected with each other at the front of the casing, as at 14, Fig. 4,

and also at the rear by diving ducts 15,

Fig. 6. These ducts communicate with the rear end of a mixing chamber 16 which is disposed directly above the tunnel 11, as best shown in Fig. 2. A

Said mixing chamber is desirably circular in transverse section and is preferably of a length approximately one-half that of the casing. Extending downwardly into said tunnel from the forward end of the chamber 16 is an air supply passage 17.

18 represents a'tubular cylindrical damper or valve rotatably supported by stirrups 19 which are secured to the leg members 12 to cause the valve to bear against the roof of Specification of Letters Patent. l

the tunnel 11. Said valve is open at one'or 55 Aboth ends and is provided with a peripheral rotated by means of a rod 21 having a regulating finger 22 at its forward end. The top of the casing and in front of the part containing said mixing chamber is formed to provide a central longitudinal ridge 23 and a trough 24 at each side of the latter.

rTransversely disposed vertical slots 25 are provided in said ridge to afford outlets from the space 14. Vertical slots 26 are also pro- 70 vided in the outer walls 101 the leg members 12 at suitable distances apart to afford outlets from the wino' fiues 13.

Provided above the ridge 23 is an oil vaporizer in the form, preferably, of a pipe 27 arranged axially of the mixing chamber and having a nozzle-attachment 28 extending into the same. Said oil vaporizer receives oil-at its forward end by a tube 29 leading from a reservoir or other source of supply, not shown,at a pressure exceeding that obtaining in the mixing chamber.

In starting operations, cotton waste, or an equivalent saturated with oil, is placed in troughs '24 and ignited to produce heat for 85 vaporizing oil within the pipe 27. The oil gas thus generated escapes through the nozzle 2S into chamber 16 to mix with atmospheric air admitted through valve aperture 20 and inlet passage 17. 90

The combustible mixture of gas and air thereupon passes from the rear of chamber 16 downwardly through diving ducts 15 into wing fines 13, whence the admixture escapes through apertures 26 and 25 to become ig- 95 nited by the iiame caused by burning oil in troughs 24.

The burner will thereupon furnish a sulicient quantity of the combustible mixture through the slots 25 for burning Vto continue 100 the vaporizing of oil in pipe 27 and also through slots 26 which affords heat for cooking or other purposes.

The slots 26 from which the combustible gas is emitted are desirably distributed from near the front of the burner to within proximity of the diving ducts and, furthermore, by positioning the referred to slots in the side walls of the casing 10, the burner is subjected to considerable heat whereby the gas, air and the mixture thereof, are rendered quite hot in the progressive travel of the same through the mixing chamber 16, ducts 15 and iues 13 to insure a complete consumption.

The quantity of air admitted should be varied to the quality and quantity of gas generated, such regulation being attained by adjustably rotating the valve 18.

The invention will, it is thought, be understood from the foregoing description.

wWhat I claim, is-

1. In an oilburner, a casing containing a mixing chamber connected from its rear end by ,diving ducts with iues disposed at opposite sides of atunnel extending longitudin nally below said mixing chamber, said casing being providedwith an air inlet extending upwardly from the tunnel into the forward end of the mixing chamber, apertures provided in the outside walls of said dues,

a valve provided in said tunnel for regulating the admission of air into said inlet, an oil vaporizer extending into said mixing chamber, and means to supply oil into said vaporizer. 1

2. An oil burner consisting of a chamber having an air inlet at its forward end, an oil Vaporizer extending into the forward end of said chamber, a pair of fiues connected by diving ducts with the rear end of said chamber and extending for a distance in front of the chamber and below said vaporizer, apertures from said iues for the discharge of an admixture of combustible gas and air therefrom, and a cylindrical tubular valve having a peripheral port for admission of air through the interior of the valve to said inlet.
